Document Summary

Definition: a statement is a sentence used to make a claim. Statements are capable of being either true or false. The most basic concept of critical thinking. The property of being either true or false is what distinguishes a sentence from a statement. Definition: propositions that can be combined in groups or sets. Definition: a set of propositions is consistent if and only if it is possible for all of the propositions in that set to be true at the same time. A set of propositions is consistent if these propositions don"t contradict each other. It is important to understand that consistency does not imply that all, or any of the propositions in a consistent set are in fact true. To logically evaluate a set of propositions as consistent is only to see that it is possible for them to be true at the same time, not that they actually are true.
